Over ten months, B7 contributed to Stellarium/stellarium by delivering user-facing features and stability improvements across rendering, localization, and UI workflows. They enhanced HiPS survey management, implemented scalable translation tooling, and improved rendering fidelity for planetary and atmospheric visuals. Using C++, Qt, and OpenGL, B7 refactored core modules for maintainability, optimized texture loading, and introduced dynamic UI scaling. Their work included cross-platform build fixes, robust logging, and data-driven approaches to sky culture localization. By focusing on code quality, performance, and internationalization, B7 enabled a more reliable, accessible, and maintainable codebase, demonstrating depth in both technical execution and architectural foresight.

May 1, 2025May 2025 highlights for Stellarium/stellarium: Delivered a user-facing enhancement to the Lens Distortion Estimator to optionally preserve image placement on new image loads, improving workflow predictability. Implemented code quality and maintainability improvements across the HiPS code path and the broader codebase, including refactoring HiPS tile texture binding into a dedicated bindTextures method, removing redundant auto-generated comments, and updating clang-format for consistent coding standards. No major bugs fixed this month; focus remained on stability, quality, and long-term maintainability. Demonstrated skills in C++, plugin development, HiPS handling, and systematic refactoring with automated formatting.
